@Stephane-Foloppe about a couple of months ago one of the onion admins stated that onion was going to build a whole new wifi driver. i think he stated that it would be ready around sept. 1st. i don't think it has been finished since i'd guess they would have released a new firmware build by now. anyway, that's what i've read about wifi recently.

@Stephane-Foloppe i'm not sure if you know that for the most part this is a user to user community forum. some admins from onion post every once in awhile but they have not had a large presence. but there are some really knowledgeable people [i'm not one] who will help you out best that they can. but yes, i think many of us agree that it's a disappointment.
